Service loop for top drive equipment having an embedded lay line

Abstract

A top drive service loop cable assembly including a plurality of cabled internal cable components a jacket covering the internal cable components, and a flange connected to the jacket and supporting sat internal cable components. The jacket has an embedded lay line embossed into the cable, aligned with internal cable components.

The invention claimed is: 
     
       1. A top drive service loop cable assembly comprising:
 a plurality of cabled internal cable components; 
 a jacket covering said internal cable components; 
 a flange connected to said jacket and supporting said internal cable components, 
 wherein said jacket has a recessed embedded lay line embossed into said cable and aligned with internal cable components, 
 wherein said recessed embedded lay line is impressed into uncured rubber of said jacket with a nylon tape coated with a release agent which is impressed into said uncured rubber via a mold extruder, during extrusion, and 
 wherein said jacket is vulcanized and then said nylon tape is removed, leaving said embossed and recessed embedded lay line in said jacket. 
 
     
     
       2. The top drive service loop cable assembly as claimed in  claim 1 , wherein said embedded lay line is a recessed embossed area. 
     
     
       3. The top drive service loop cable assembly as claimed in  claim 2 , wherein said embedded lay line is a recessed embossed area that is 0.019″ deep and 0.375″ wide. 
     
     
       4. The top drive service loop cable assembly as claimed in  claim 1 , wherein said jacket is made from either one of Chlorinated Polyethylene (CPE) or Thermoplastic polyurethane (TPU).
